Omsk hemorrhagic fever (OHF) is caused by Omsk hemorrhagic fever virus (OHFV), a member of the virus family Flaviviridae. OHF was described between 1945 and 1947 in Omsk, Russia from patients with hemorrhagic fever.

Rodents serve as the primary host for OHFV, which is transmitted to rodents from the bite of an infected tick. Common tick vectors include Dermacentor reticulatus, Dermacentor marginatus, Ixodes persulcatus and common rodents infected with OHFV include the muskrat (Ondatra zibethica), water vole (Arvicola terrestris), and narrow-skulled voles (Microtus gregalis). Muskrats are not native to the Omsk region but were introduced to the area and are now a common target for hunters and trappers. Like humans, muskrats fall ill and die when infected with the virus.

OHF occurs in the western Siberia regions of Omsk, Novosibirsk, Kurgan and Tyumen.
